Build up new Spymasters instead of charging for replacements

[XxFran10xX]

Summary

Replacing a Spymaster no longer costs the treasury. A new Spymaster now has to build up their network instead, and the leader has to wait between appointments.

• No treasury cost. espionage.appointments.repeat-cost is retired and is removed from existing special-positions.yml files on load (added to Make the faction leader the default holder of special positions #136's RETIRED_KEYS). The "Replaced Spymaster" unrest stays (stability-penalty / penalty-days, set either to 0 to turn it off).
• Build-up. A newly appointed Spymaster starts at starting-aptitude (default 0.25) of their aptitude and rises linearly to full over build-up-days (default 7). This applies to daily offense/defense rolls and the aptitude shown in menus and foreign reports. Make the faction leader the default holder of special positions #136's extra-position penalty stacks on top. build-up-days: 0 turns it off.
• Change wait. After an appointment, the leader cannot appoint another Spymaster for change-cooldown-days (default 2). Dismissing the appointee is still allowed at any time (the office returns to the leader, per Make the faction leader the default holder of special positions #136), but it does not reset the wait, so dismiss-then-reappoint can't skip it. If the appointee's character dies, the wait is waived. An appointee who leaves or is kicked does not waive it. 0 turns it off.
• Existing offices. Founders, the leader's default holding (Make the faction leader the default holder of special positions #136), and Spymasters saved before this change have no appointment time, so they keep full aptitude and nothing blocks their faction's next appointment.
• GUI and messages. The Spymaster office, private conduct and candidate menus now show build-up progress, the build-up terms and when the next appointment is possible, in place of the treasury cost.

Rebased onto #136 (leader as default holder). Docs: TF-Minecraft/Docs#102.

Testing

• mvn -B verify after the rebase: 2693 tests, 0 failures.
• New and updated tests cover cost-free appointments, build-up maths (start, midpoint, full, clock skew, disabled), the wait (blocked, persisted across a save, survives dismissal, waived on death, disabled), config bounds, retiring repeat-cost, and rollback of the wait when a save fails.
• TFMCDev01: a Make the faction leader the default holder of special positions #136 + Build up new Spymasters instead of charging for replacements #137 build loaded cleanly at 20:34 UTC (SimpleFactions enabled without errors, new config keys added).

📝 Summary

Summary by CodeRabbit

• New Features
  • Spymaster appointments now have a configurable cooldown. Removing an appointee does not clear the wait, but a holder’s death waives it.
  • New appointees’ aptitude builds over a configurable period towards its full level. Menus show current aptitude and build-up progress.
• Changes
  • Appointments are now free. Replacing a Spymaster can cause unrest that fades over a configurable period; automatic founding appointments do not count as replacements.
  • Appointment options and status messages show cooldown availability, aptitude and any unrest from a replacement.

Walkthrough

Spymaster appointments no longer use treasury costs. Configurable cooldowns govern deliberate replacements, and office state stores appointment timestamps. Aptitude builds up over time. Menus and messages display appointment availability and build-up status.

Merge Risk: ⚪ Minimal · up to d5573

The previously tracked aptitude-display concern is addressed, and no remaining issue in the supplied changes warrants delaying the merge.

Security Architecture Review

Security architecture risk: 🔵 Low · up to d5573

Appointment actions remain permission-checked, and dismissal cannot bypass the new wait. No authorization bypass was identified. The main remaining uncertainty is downgrade behavior after saved timing data and configuration have changed.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The intended exposure change is faction-wide intelligence quality: a building-up defender can produce weaker defense rolls against rival factions. Outcomes are shared daily faction reports, and the existing protection decision also covers guild information. This is a gameplay disclosure change, not evidence of infrastructure or credential access.

Trust Boundaries and Controls

• observed — GUI candidate metadata is not authoritative. The service rechecks current leader authority, candidate online status and faction membership, active character identity, duplicate appointment, and cooldown before mutation. Private conduct changes require the current holder's identity. Character-death cleanup is scheduled for the next server tick and checks committed death status.

Hardening Proposals

• proposed — Preserve the pre-upgrade special-position configuration and faction saves when preparing a downgrade, so retired treasury settings and appointment timing can be restored deliberately.

@coderabbitai The starting-aptitude finding is fixed in d55730a (buildsUp() guards both the remaining time and the menu text, with a test). Please resolve your comments and approve.
